The paper presents the design and implementation of an electrical control panel for the automatic control of a ventilation system serving three independent CNC woodworking machines. The purpose of the automation system is to open and close the airflow from the operating machines to a central filtration unit, preventing the ingress of dust particles from operating machines into non-operating ones.

The process is activated by the switching on or off of any of the three machines independently, and according to a predefined algorithm, the system controls the cleaning (shaking) mechanism of the mechanical filters. In addition, a rotary airlock is controlled for collecting fine dust particles after the cleaning process into a dedicated storage container.
